Tg of methyl acrylate
WebGlass transition temperatures of cyclic and linear PS were determined by DSC.159 For linear PS, the dependence of T g on molar mass can be expressed by Tg = [1/ Tg + K / Mw] −1, where K is a polymer-dependent constant and Mw is the weight average molar mass. An alternative formulation for PS is given by ΔTg = Tg ∞ – Tgi = –10 5 / Mn ...

Did you know?
WebWhen you have the methyl group on the double bond (of a methacrylate ester), then you have hydroxyethyl methacrylate, also known as HEMA; see the structure below for the monomer and polymer. The polymer has useful properties, being reactive and liking to bond with lots of other polar functional groups.
